Abstract

Labyrinth drainage for draining and suctioning wound exudate and body fluids from human or animal bodies, characterized in that a textile labyrinth (6) is embedded in two perforated foils (25) which can be individually adapted inside and outside by cutting (3), which is embedded by means of a Connection (10) are connected and can be sucked through the special labyrinth (19) wound exudate (11).

Description

The invention describes a labyrinth drainage, which is focussed by cutting with respect to the outer shape and corresponding to the interior of the respective special wound, e.g. a wound around a stoma, can be individually adjusted and by embedding a special labyrinth between an upper and lower film, which is very soft and flexible, no perforations occur in the wound area.

It is a common task in medicine to aspirate wound fluids. In particular, in the case of deep, large and in particular infected surface wounds, the usual practice to date is to insert a wound dressing into the wound which does not grow together with the tissue. The doctor applies a first layer of gauze to this wound dressing, into which a drainage tube, some of which is wound several times, is then placed by hand and covered again with a second layer of gauze and then the entire wound site is covered with a plaster. A vacuum is then applied to the end of the drainage hose, which means that the wound fluid can be sucked off.
In addition to the long duration of the time required for the laying of the means described above, this procedure also requires considerable skill on the part of the physician caring for the wound, because all separately inserted device components have to be fixed during wound care, which often cannot be accomplished by one person alone.

Another type of wound dressing that was developed especially for vacuum wound treatment is, for example, in DE 601 18 546 described.
The wound dressing described there, on the one hand, requires a relatively high production outlay and, on the other hand, is not readily adaptable to different wound sizes. On the other hand, in order to carry out a vacuum treatment, this solution requires further, relatively complicated additional supports and, as a rule, bell-like seals on the wound, to which an external vacuum connection is attached.
Such designs, which far surpass the surface of the skin, considerably restrict the patient's freedom of movement and, moreover, create unpleasant additional pressure loads.

The treatment of such wounds outlined under negative pressure, as outlined above, has been a method which has been practiced for many years and which has a positive effect on the healing of deep and large wounds by permanent wound irritation. This type of vacuum wound treatment is, for example, in DE 694 25 881 T3 . DE 692 29 940 T2 and DE 692 24 847 T3 described in detail why it should only be referred to here.

There are also a number of other solutions, but these are only to be listed here as examples because they relate to technical solutions that are further away. So that's it US 6,695,824 B2 a wound dressing cover for outer flat wounds is known, which consists of two layers, the first layer being placed directly on the wound and the second layer having an external moisture barrier.

A plurality of hose-like supply lines are provided between the layers mentioned, which ensure that the wound is supplied with moisture.

However, the aforementioned wound dressing cover is not designed and not suitable for use in the context of wound treatment of deep, poorly healing wounds with the aid of the vacuum wound treatment technique, because it is practically impossible for the tubes, some of which are provided several times, to be removed from the wound area in a vacuum-tight manner.
The same applies to a variety of devices for suctioning wound secretions from body cavities, such as in EP 1 764 127 A1 described.

Furthermore, in the EP 2008/003251 described a surface drainage with a lead tail.

The present invention is primarily based on the task of creating a surface-like, flexible, soft drainage which can be cut both outside and inside and which can be placed individually around a stoma or on the stoma or similar wound forms. The object of the invention is achieved by the characterizing features of patent claim 1.
Advantageous refinements are the subject of the subordinate claims.

The invention is explained in more detail in the attached schematic drawings.

The 1 shows a ring drainage ( 1 ), which consists of a perforated bottom and top film ( 25 ) with embedded labyrinth ( 6 ), where the perforation ( 8th ) to the mark ( 13 ) of the strand ( 4 ) in the perforation length ( 7 ) is trained.
Through the opening ( 2 ) can be cut ( 3 ) adaptation to a stoma ( 21 ) and a wound ( 20 ) respectively.
Using a suction hose ( 9 ) can be connected to a connection after connecting a vacuum pump ( 5 ) Wound exudate ( 11 ) are suctioned off.
The top and bottom film ( 25 ) are with the embedded labyrinth ( 6 ) connected by a connection. This means that when storing a special labyrinth ( 19 ) also by a border cut ( 26 ) the external form of drainage of the wound ( 20 ) be adjusted.

In the 2 are different drainage forms in the scope of the invention as surface drainage ( 15 ), Drainage line ( 16 ), Elliptical drainage ( 17 ) and circular drainage ( 18 ). In the area drainage ( 15 ) are the top and bottom film ( 25 ) with enclosed labyrinth ( 6 ) by a weld seam ( 14 ) connected.
For the positions ( 16 ), ( 17 ) and ( 18 ) is the connection ( 10 ) a seam, as a special labyrinth ( 19 ) is applied, which is also an individual cut ( 3 ) allowed without creating a risk of perforation for organs caused by sharp cut edges.

The application of the invention with the focus on stoma drainage is in the 3 shown.
The ring drainage ( 1 ) is in the wound ( 20 ) to the stoma ( 21 ) embedded.
If leaks and irregularities in the stoma ( 21 ) and on the adhesive seal ( 24 ), excrement ( 22 ) in the wound ( 20 ) and ring drainage ( 1 ) and strand ( 4 ) are suctioned off.
Above the stoma ( 21 ) is a stoma pouch ( 23 ) on the adhesive seal ( 24 ) attached. Wound exudate formed ( 11 ) is also removed from the wound area of the wound ( 20 ) suctioned off.
